Technical Field

[0002] An air compressor is a device used to compress gas. Its structure is similar to that of a water pump. Most air compressors are reciprocating piston type, with rotating blades or a rotating screw. The main function of an air compressor silencer cover is to reduce the noise generated during the operation of the air compressor. According to the "A Silencer Cover for a Refrigeration Compressor" provided by Chinese Patent Authorization Publication No. CN220354002U, the above-mentioned document mainly adopts a split design, allowing noise to propagate within an annular channel, creating a buffering effect. However, this split design is easily damaged, and relying solely on the annular channel to buffer noise is not ideal. To this end, we provide a silencer cover for an air compressor to solve the above problems. Utility Model Content

[0004] Preferably, the inner cavity of the silencer cover is located at the end of the noise propagation and is fixed with two rods, and the two rods are arranged in parallel. The outer wall of the rod is provided with a spring, and the inner cavity of the silencer cover is provided with a buffer plate, and the buffer plate is provided with a socket at the position corresponding to the rod, and the rod is slidably connected to the corresponding socket.

[0011] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.
[0012] The utility model proposes a silencer cover for an air compressor, comprising a silencer cover 1, a partition 2 fixedly provided at the bottom of the inner cavity of the silencer cover 1, a plurality of air holes 3 opened inside the partition 2, and the plurality of air holes 3 are equidistantly distributed, a plurality of guide plates 4 are fixedly provided on the inner wall of the silencer cover 1 above the partition 2, so that a serpentine channel is formed between the silencer cover 1 and the guide plate 4, a plurality of buffer strips 5 are fixedly provided on the outer wall of the guide plate 4, and two corresponding buffer strips 5 are correspondingly arranged to form a buffer zone between the guide plate 4 and the buffer strips 5, noise can enter the silencer area of the silencer cover 1 through the air holes 3 of the partition 2, and propagate in the serpentine channel of the guide plate 4, and during the propagation process, a noise buffer zone can be formed by utilizing the design of the buffer strips 5, and the noise can be further gradually weakened during the propagation process.
[0013] Specifically, the inner cavity of the silencer cover 1 is located at the end of the noise propagation and is fixed with two rod bodies 6, and the two rod bodies 6 are arranged in parallel. The outer wall of the rod body 6 is provided with a spring 7, and the inner cavity of the silencer cover 1 is provided with a buffer plate 8. The buffer plate 8 is provided with a socket 9 at the position corresponding to the rod body 6. The rod body 6 is slidably connected to the corresponding socket 9. When the noise reaches the end of the serpentine channel of the silencer cover 1, the noise can bounce the buffer plate 8 to move backward, and achieve a buffering effect under the action of the spring 7, and finally achieve a buffering reset of the buffer plate 8.
[0014] Specifically, a block 10 is fixedly provided at one end of the rod body 6 close to the buffer plate 8. The diameter of the block 10 is larger than the inner diameter of the socket 9. The design of the block 10 can prevent the buffer plate 8 from separating from the rod body 6. At the same time, in actual use, a rubber pad is added to the outer wall of the end of the rod body 6 close to the block 10 to reduce the impact of the buffer plate 8 on the block 10.
[0015] Specifically, the buffer strip 5 is tilted, and the angle between the buffer strip 5 and the guide plate 4 is set between 30° and 50°. This design can better form a noise vortex, so that the noise can be stably buffered and eliminated therein.
[0016] Working principle: When using the silencer cover 1, the staff can fix the silencer cover 1 on the air compressor. When the air compressor is working, it will generate noise, and the noise can enter the silencer area of the silencer cover 1 through the air holes 3 of the partition 2 and propagate in the serpentine channel of the guide plate 4. During the propagation process, a noise buffer zone can be formed by using the inclined buffer strips 5. The noise can be further gradually weakened during the propagation process. When the noise reaches the end of the serpentine channel of the silencer cover 1, the noise can bounce the buffer plate 8 backward and achieve a buffering effect under the action of the spring 7. Finally, the buffering reset of the buffer plate 8 is achieved. This design can not only buffer the noise through the serpentine channel, but also buffer in the buffer zone of the buffer strip 5. Finally, the noise is completely eliminated through the buffering of the buffer plate 8. The one-piece design of the silencer cover 1 ensures the rigidity of the silencer cover 1 and has certain practicality.
